Childhood Diseases

Dear Dr,

I took my LG who is now 17w to the Paed on Saturday, as she had a very bad cough for 2 nights before. It sounded dry, almost like a dog barking with a sore throat, at night, but during the day was a wet cough. She also struggled to breathe at night, and I was concerned that it could be wheeping cough. Paed said that her tonsils are enlarged, and prescribed Bisolvon and Zithromax, as she's been on Orelox twice before for a chest and bladder infection - apparently this is quite common in reflux babies. She did not respond well to the Orelox, and threw up constanly. She was given only 2ml Zithromax for 3 days. I read that the most common side effects of Zithromax is winds, stomach cramps and heartburn, which she already suffers from due to the reflux. Last dose of Zithromax was on Monday, but since then still has the same symptoms, except that the coughing is MUCH better, although it still sounds as if she has some trouble to breathe every now and again at night. She also seems to have started teething, as she is constantly busy with her gums and when she really cries, and I use some Pansoral, she's a bit more relaxed. The problem is that she cries when having her milk since she started getting sick, and it still isn't better. She is very hungry when she takes her bottle, and drinks about 50 - 70ml, takes the bottle out and refuses to drink again. She screams when you bring the bottle near her, and it takes about an hour to two to get her to have most of her milk, but it really is a struggle. Could this be caused by teething or reflux? What should I do? She does not have a fever anymore and mostly seems happy, just not during feeding suddenly.

Thank you in advance. Sorry for the long post.
Daisy.
